QPECI'PICATION forming part of Letters Patent No. 391,787, dated October 30, 1888.

Application filed May 3, 1888. Serial No. 272624. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL FRIEND, of the the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Ohurns, of which the following is a specification.

My invent-ion consists in the means for making butter hereinafter set forth and claimed. My invention operates by forcing air into [0 or through the milk or cream while the same is being more or less agitated, and comprises the mechanism set forth in the drawings, in which I Figure 1 represents a cream-receptacle in central vertical section with my devicein operative connection therewith, and Fig. 2 represents the bottom of the disk and the fans or heaters that create the air-current.

The creanrreceptacle is indicated by refer- 2 once-letter a. b represents a bracket that provides bearings for shaft 0 and the shaft of drive-wheel c. Drivewheel c hasa crank-arm, c,.and is geared to mesh with the pinion (Z on shaft 0. Near the lower end of shaft 6 is disk f, perforated at h h h h. (See Fig. 2.) The disk is smaller in diameter than the adjacent internal diameter of the receptacle, and is provided on its lower surface with fans or beaters i t i i. Fitting close to the top of the disk and encircling the shaft is air-ductg. Projecting upward froni'the bottom of the receptacle,outsidc the path of the fans, are pins It in any desired number.

In Fig. 1, Z represents aclamp -support for 5 5 butter-gatherer m. The gatherer is preferably slotted at m, and it has a handle, it, provided with a projection, 0, that rests on the clamp support and sustains the gatherer.

In operation the shaft is rapidly rotated in 40 the direction indicated by the arrow in Fig. 2.

The fans beat the cream against the pins and also establish a strong current of air in the direction indicated by the arrows in Fig. 1. The air-current is effective in breaking the butter-sacs, and it also tends to force the cream above the disk, where the butter may be readily gathered. 'Ihe gathcrer, which is a desir able but not indispensable concomitant of my device, may be manipulated to swing more or less near the air-duct, according as greater or less resistance to the rotative force of the mass of butter is required to form a ball.

I claim as new and desire to secure by Letters Patent 1. Ina churn, the combination, with the milk or cream receptacle, of vertical shaft 6, carrying the horizontal perforated disk f, provided on its upper side with an open tubular air-duct, g, which surrounds said shaft and perforations, and on its under side with fans or beaters 1', partially surrounding said perforations, as set forth.

2. In a churn, the combination, with the milk or cream receptacle having pins k, of vertical shaft 0, carrying the horizontal perforated diskf, provided on its upper side with an open tubular ainduct, g, which surrounds said shaft and perforations, and on its under side with heaters i, as set forth.

3. In a churn, the combination, with the milk or cream receptacle having pins k and supporting pivotally a gathering-plate, m, of shaft 6, provided with horizontal perforated diskf, carrying upon its upper side the tubular air-duct g and on its lower side the boaters 'i, as set forth.

In testimony whereof I'sign my name in the presence of two subscribing witnesses.

SAMUEL FRIEND.
